The embodiment of the invention discloses a method and device for controlling the torque of an engine, electronic equipment and a storage medium. The method for controlling the torque of the engine comprises the steps that the gear state of a vehicle, the running state of the engine and the charge state value of a power battery are obtained; according to the gear state, the engine running state and the power battery charge state value, the vehicle working condition is determined; under the condition that the vehicle working condition is the preset working condition, the stage of the vehicle working condition is judged according to the charge state value of the power battery, and a stage judgment result is obtained; obtaining an engine demand torque value corresponding to the stage judgment result; and controlling the engine according to the required torque value of the engine. Thus, the corresponding engine demand torque value is obtained according to the stage of the vehicle working condition, the state-of-charge value of the power battery can reach the balance infinitely approaching the rated upper limit value, the engine is prevented from entering the zero-torque self-idling working condition, and therefore the problem of tooth knocking caused by self-idling of the engine in a hybrid power system is solved.

    本申请的实施例揭示了一种控制发动机扭矩的方法、装置、电子设备及存储介质,该控制发动机扭矩的方法包括:获取车辆的档位状态、发动机运行状态和动力电池荷电状态值;根据档位状态、发动机运行状态和动力电池荷电状态值确定车辆工况;在车辆工况为预设工况的情况下,根据动力电池荷电状态值对车辆工况所处的阶段进行判定,获得阶段判定结果;获取阶段判定结果对应的发动机需求扭矩值;按照发动机需求扭矩值对发动机进行控制。这样,根据车辆工况所处的阶段获取对应的发动机需求扭矩值,能够使动力电池荷电状态值达到无限趋近于额定上限值的平衡,避免发动机进入零扭矩的自怠速工况,从而解决混合动力系统中发动机自怠速导致的敲齿问题。
